Hello emid,
welcome !
There hasn't changed a lot during the later revisions. You will be fine with any bom after 2012/2013 or so.
There also must be some mouser carts made ready to order by members. Just look through the
official GSSL help thread. Everything you need is there. It is a lot to read through, i know.. (especially when you got errors to fix) but it will help you learning and understanding DIY.
I also recommend reading one of Gustav's (pcbgrinder.com) assembly guides of the gyraf ssl. Especially as a newbie this helped me a lot understanding everything.
Anyway, i attached a BOM for you, hoping this is going to help you. I'd recommend asking anything gssl related in the thread i linked above.
